I can't watch the video at the moment due to a proxy but from what i read in the comparison on the autobild-homepage the 328i won it:

"Der BMW 328i hat mehr Kraft, er weckt die Lebensgeister, und er leistet sich auch im täglichen Gebrauch keine Schwächen. Meisterhaft."

"The BMW 328i has more power, awakens your spirits, and he doesn't have any weaknesses when it comes to daily driving. Masterful."
